Thanks a lot for the support, guys!

I've found some style I like and that I seem to be actually able to do, so...

@Falconius: thanks for the better translation. Concerning the nose/pheromone question, the nose is mainly for breathing, and a part of the pheromone/scent abilities of the aristeans. Basically, a large part of the face is concerned : the pheromonal slits and the excretory organ are playing their parts. I must confess it's also part of an aesthetic choice, aristean being one of the most "human-like" of the species.
